GEORGE T. SNYDER, OF IVILMINGTON, DELAWARE, ASSIGNOR TO HIMSELF A NDGEORGE w. 'A REY, vOF BALTIMORE, MARYLAND.

Letters Patent No. 94,143, dated August 24,1869.

The Schedule referred to in these Letters Patent and making parte! thesame.

thereof, reference being had to the accompanying drawings, and to theletters Yof reference marked thereon, which form a part of thisspecification, and in whichvFigure 1 represents a transverse verticalsection, and

Figure 2, a side view of my improved revolving vessel.

Similar letters of reference indicate like parts in both figures ofthedrawings.

The nature of my invention consists- First, in the novel arrangement ofa pilot-house, in relation to a revolving vessel;

Second, iu the construction and arrangementof a hollow shaft or tube andsmoke-stack, whereby smoke and steam from an engine-furnace may becarried olf,

Third, the combination of' a segmental platform or car andcentrally-arranged shaft, whereby said car is suspended from the centreof the vessel, as will be hereafter more fully described. v

To enable others skilled in the art to make and use my invention, I willnow describe the construction and operation ofthe parts.

In the accompanying drawings y A represents a cylindrical vessel,providedwth a suitable number of flanges, a a, and to which are se'cured thebuckets or paddles b b.

The vessel A 'is designed to roll or revolve upon either land or water,the flanges b b protecting the paddles-when usedom land, and is to bepropelled by power and machinery, adjusted inside of said Vessel.

Inside of the vessel A, are secured and arranged two or more insidegear-wheels, b b', which serve as racks, and which are operated'upon andcaused to revolve by the pinion's c e, which, in turn, are propelled bymeans of a steam or other engine, p, adjusted upon and connected withthe oscillatingsegmental carD.

The pinions e c are secured upon the shaft B, which has its bearings inthe car D, asI will be seen by reference to the drawings.

The segmental car D is made, as shown, so as to fit inside of the hollowdrum or vessel A, and is proand are secured in the centre of the ends orheads of' the Ivessel A.v

The central shaft E extends out somewhat beyond the ends of tlie vessel,`and has the tubular or hollowr posts K K securely fastened thereto, aswell as the pipe or smoke-stack O. 1

It'will readily be seen that the central-shaft being hollow, it willserve the place of a flue, and conduct the smoke out into the stack ortube O.

L represents a beam, extendingacross and-near the outer; surface of thevessel, and Aisframed with the upright posts K K, ,and supports thepilot-housetF, as fully shown.

M M represent arms, pivoted to the ends of the central shaft E, andwhich have framed therewith a cross or connecting-beam, N, to which ispivoted the rudder P, by m'eans of a metallic strap or plate, O.

The rudder I? is operated by means of cords or ropes,Vl

extending from'the pilot house, as shown, or in any' suitable m'anner. p

It will be seen that the weight of the machinery and cargo will keep thecarD always in nearly a horizontal position, the whole being suspendedfrom or by means of the central shaft E, the' advantages of whichmustbeobvious. l

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent,'is-- p i 1.The pilot-house F, when supported upon, and by means ofthe crosseheam L,posts' K K, and central shaft E, as set forth.A

2. The centralhollow shaft E, in combination with the tube orsmoke-stack C, as herein described.

3. The combination of the-'segmental car D with the centralsuspending'shaft E and a revolving vessel, A, as and for the purposespecified.

4. The combination ofthe internal gear-wheels b' b and pinions c e, whensaid pinions are suspended by the car D, as specified. l I

In testimony that I claim the foregoing as my own, I aix my signature inpresence of two witnesses.

GEORGE T. SNYDER.
